Fig. 5 is the block diagram of control exemplary system 500.In some embodiments, control system 500 can be used for, and for instance, control is the described parts of dissemination system shown in Fig. 1-4 just.In other embodiment, control system 500 possibly be applicable to alternative dissemination system.Usually, control system 500 utilizes controller 505 operation magnetic valve 510, material metering device 515 and dissemination system status indicator 520.In addition, controller 505 acceptance are from the information of one or more sensors 525 (for example, conductivity sensor).In some embodiments, possibly use other sensor, will describe in more detail below.
Usually, controller 505 is suitable electronic installations, for example, for instance, programmable logic controller (" PLC "), personal computer (" PC ") and/or other industrial calculation element/dedicated computing device.Equally, controller 505 possibly comprise the hardware and software composition, and means the combination of including this constituents widely.In some embodiments, magnetic valve 510 is normal closed gates of opening when encouraging receiving.For instance, controller 505 sends the signal of opening magnetic valve 510 to magnetic valve 510.Material metering device 515 can be used for controlling the quantity from the material of container distribution.For instance, in some embodiments, metering device 515 is similar with the end socket 115 shown in Fig. 1-4.Be similar to magnetic valve 510, metering device 515 is by the signal controlling of coming self-controller 505.Status indicator 520 possibly comprise one or more visions and/or audible indicator (for example, lamp, LCD (" LCD ") unit, loudspeaker, or the like), so that point out the situation (for example, as described about Figure 20) of dissemination system to the user.In some embodiments, sensor 525 is simulation conductivity sensor, and this sensor sends the conductive variable signal of indication sensor 525 peripheral regions (for example, the signal of the signal of 0-10 volt, 0-10 milliampere, or the like) to controller 505.
When operation, usually, the information that controller 505 is used to autobiography sensor 525 determines how this controls magnetic valve 510, metering device 515 and dissemination system status indicator 520.For instance, in some embodiments, during material delivery cycle (for example, distributing the circulation of the material of one or more dosage), controller 505 sends signal to magnetic valve 510 at first, gives magnetic valve 510 power supplies.In case power supply, magnetic valve 510 just allows water flows.This initial water injects can be called preparatory flushing.In addition, controller 505 is by accepting conductivity information from the signal of sensor 525.For instance, in some embodiments, when material mixed with water, solution had more conductibility than water itself in fact.Therefore, the conductibility of sensor 525 energy measurement water and/or water/material solution, and produce the corresponding signal that sends controller 505 to.Whether controller 505 utilizes the conductivity information decision to be distributed to the material of one or more dosage in the mobile water.If controller 505 determines not work sheet, controller 505 possibly produce distribution erroneous condition signal, and this signal is transmitted to status indicator 520, points out this mistake then.After dosing, controller 505 maintenance magnetic valves 510 are in excited state and clean up the material of being sent with the water that allows to flow.These current can be called as afterflush after dosing.After afterflush and/or between post-flush period, whether the conductivity information verification material that controller 505 also is used to autobiography sensor 525 is suitably managed by components downstream and/or is accepted.If controller 505 definite these materials are not suitably managed by components downstream and/or accepted, controller 505 possibly produce distribution erroneous condition signal, sends status indicator 520 to, and this status indicator is pointed out this mistake then.
In some embodiments, control system 500 possibly comprise the input unit that allows user's input and control the changeable setting of one or more users.For instance, the user possibly use this input unit input material quantity (for example, the some dosage that will send), the length of flushing in advance and/or the length and/or the quantity of quantity and afterflush.In some embodiments, for instance, flushing was adjusted between about 1.5 seconds and 5 seconds aspect the duration in advance, and afterflush can be adjusted between about 2 seconds and 10 seconds aspect the duration.In addition, as that kind that is described in more detail below, the user can import one or more conductivity threshold, and controller 505 can use this threshold value whether to determine delivery materials.
In some embodiments, control system 500 possibly comprise than those parts of Duoing shown in Figure 5.In one embodiment, the diverse location that control system 500 is included in dissemination system is measured conductive a plurality of sensor.For instance, shown in Fig. 4 B, first sensor is used for measuring and the verification current near being placed on inlet channel, and second sensor is placed near the conductibility that outlet conduit, is used for measuring water/material solution in the container.In addition, downstream sensor can be added in the control system 500, measures the conductibility (for example, in washing machine or dish-washing machine) of water/material solution after solution leaves container.In another embodiment, control system 500 possibly comprise the communicator that allows control system 500 and other system communication.For instance, in some embodiments, the material quantity that can be used to distribute can be followed the trail of by control system 500, and when material horizontal is enough low, sends notification signal to another system.Control system 500 also possibly send one or more other systems (for example, central control system) to operation information (for example, dose quantity, the flushing and length, the dissemination system mistake of afterflush in advance, or the like) to.In addition, control system 500 maybe be by communication system by another system's control.
In some embodiments, controller 505 possibly produce distribution erroneous condition signal because be different from the reason of above-mentioned those.For instance; (for example comprising a more than sensor 525; A sensor 525 is placed near the inlet channel; A sensor 525 is placed near the outlet conduit) embodiment in, if inconsistent from the signal of sensor 525, controller 505 possibly produce distribution erroneous condition signal.For instance, if pointed out water near the sensor of inlet channel 525, but point out there is not water near the sensor 525 of outlet conduit, the distribution erroneous condition possibly be identified.In another embodiment, if identify problem (for example, communication system can not send information to other system), possibly produce the erroneous condition signal about communication system.
Fig. 6 illustrates the program 600 of during material delivery cycle, using the operation of control system (for example, control system 500) control dissemination system (for example, dissemination system 100).In some embodiments, whether program 600 also can be used for investigating material by the indication of suitably sending and providing how many materials to be sent.Though it is that parts by being included among dissemination system 100 and/or the control system 500 are implemented that program 600 is described to, in other embodiment, program 600 can be applicable to other system.
The first step of program 600 is the conductibility (step 605) in the beginning containers 110.This possibly be done in such a way that for instance, through initialization conductivity sensor 525.In some embodiments, conductivity sensor 525 is ongoing operations, produces and sends the conductive signal of indication of controller 505 to, and need not be initialised.Next, be supplied to container 110 (step 610) to water in the flushing operation in advance, and investigating conductive change (step 615).For instance, whether controller 505 conductibility that verification is monitored with sensor 525 when adding water changes.Controller 505 can be through comparing verification from the conductibility signal of sensor 525 and one group of conductivity threshold that stores or whether the variation of definite conductibility is suitable.With regard to Fig. 6, conductibility relatively is (for example, the conductive change) generally described.Yet the more time dependent specific curves exemplary of conductibility are that Fig. 7-19 provides.These curves provide some particular example, and conductive numerical value will compare with one or more conductivity threshold in these examples, in order that whether discern conductive numerical value suitable.
The comparative result of conductivity values and conductivity threshold can help also to confirm whether the distribution erroneous condition exists.For instance, if do not change according to limit of in controller 505, setting that belongs to material delivery cycle or threshold value, then possibly point out to distribute erroneous condition (for example, showing) (step 620) with status indicator 520 with the conductibility of sensor 525 monitorings.For instance, in some embodiments, status indicator 520 can use the lamp battle array to point out to distribute erroneous condition (for example, as as described in Figure 20).In another embodiment, as discussed previously, status indicator 520 can use LCD unit or similar visual device to point out to distribute erroneous condition.As replenishing or substitute, audible alarm possibly be used for pointing out to distribute erroneous condition, and perhaps information possibly be sent out.As that kind that is described in more detail below, the distribution erroneous condition possibly comprise " anhydrous " situation, " dispensing device obstruction " or " blocked flow path " situation and/or " shortage product " situation.Other distribution erroneous condition also is possible (for example, " driving malfunction " situation, " solenoid valve failure " situation, or the like).In addition, some situations (for example " blocked flow path " situation) can still be that downstream cause at the sensor upper reaches so that point out this situation by further refinement actually.
Still with reference to Fig. 6, if change to some extent according to limit or the threshold value in controller 505, set with the conductibility of sensor 525 monitorings, so, controller 505 will determine whether to distribute the material (step 625) of one or more dosage.If controller 505 determines no longer work sheet, then possibly point out to distribute erroneous condition (step 630).Such decision possibly made, and for instance, if change with the conductibility of sensor 525 monitorings, but should change with specific conductivity threshold inconsistent.If material, the dosage that distribution is such and the measurement conductibility (step 632) in dosing of controller 505 one or more dosage of decision distribution.The next procedure of program 600 is to confirm whether suitably change (step 635) in the conductibility with sensor 525 monitorings during the dosing and/or after dosing.If conductive change is inappropriate or not change completely aspect conductibility, then possibly point out to distribute erroneous condition (step 637).If it is suitable that conductibility changes, then accomplishes material delivery and start post-flush operation (step 640), and investigate last conductibility variation (step 645).If last conductibility changes inappropriate or conductibility does not change completely, then possibly point out to distribute erroneous condition (step 650).If conductive change is suitable, then program 600 finishes (step 655), and material delivery cycle is accomplished.In accomplishing, whether controller 505 can be confirmed or investigate material and suitably sent.Controller 505 also can be through confirming sending how much dosage confirms to send how many materials (for example, seeing step 632).Program 600 is just to move once whenever starting material delivery cycle.
In other embodiment, alternative program possibly be used for giving container 110 material delivery.For instance, in some embodiments, conductibility possibly be in other some verification during program.As replenishing or substitute, other parameter maybe be monitored (for example, material weight, inductance, turbidity, or the like) and be used to confirm whether one or more doses of material should be sent and/or whether this dosage is suitably accepted.
Fig. 7-19 illustrates conductibility exemplary change curve in time.These curves comprise and can be used for, and for instance, during material delivery cycle, confirm the conductivity trace of the situation of dissemination system (for example, dissemination system 100).For instance, in one embodiment, controller 505 can use the signal from sensor 525 to produce and those the similar conductivity trace shown in the curve.Then; Controller 505 can compare with the conductivity values and the conductivity threshold of sensor 525 monitorings; So that confirm the situation of dispenser system 100 and optionally take further action (operation of for example, reminding the user and/or sending this dissemination system of modification of signal).That kind that should be realized that as the people who originally is familiar with this technology; Curve among Fig. 7-19 only is illustrated in some examples of the conductivity values that possibly occur during the material delivery cycle, and controller 505 can be confirmed the situation of dissemination system 100 based on multiple conductivity values.Usually, as that kind that is described in more detail below, outside absolute conductibility (for example, from the size of the conductibility signal of sensor 525), conductibility changes the situation that (for example, the change aspect conductibility) can be used for confirming dissemination system 100.
Fig. 7 illustrates curve 700 exemplary, the representative of this curve when " soft " water relatively is supplied to container 110 via inlet channel 140 when during material delivery cycle desirable container conductibility (monitoring) with sensor 525.For instance, during idle periods 705, the conductibility of container 110 is lower.This is because container 110 is relatively empty or does, and solenoid 145 is in " closing " position that stops water to get into container 110.During preparatory flush period 710, solenoid is activated, and allows water to get into container 110.Thereby conductibility rises from idle level, represents the conductibility of soft water supply system.At dosing or during the distribution phase 715, driver 125 is activated, and this causes end socket 115 to be delivered to the material of one or more dosage the container 110 from container 105.Thereby conductibility rises once more, represents the conductibility of water/material solution in the container.During the dosing phase 715 since the interruption of the rotation of end socket 115 and entry material sinking possibly occur or cave in 720.After material delivery was accomplished, solenoid 145 kept state of activation, and water continues to flow through container.This back delivery period can be called post-flush period 725.During post-flush period 725, water is stayed because material is pulled away, so conductibility is fallen the level of preparatory flush period 710 soon.After post-flush period 725 was done, magnetic valve 145 lost activity (that is, water system is switched off), so level of conductivity descends.During second idle periods 730, container 110 become again relatively empty with do.
Fig. 8 illustrates curve 800 exemplary, the representative of this curve when being supplied to container 110 to " hard " water relatively via inlet channel 140 during material delivery cycle desirable container conductibility.In some aspects, curve 800 is similar with curve 700.For instance, curve 800 comprises idle periods 805, preparatory flush period 810, dosing phase 815, post-flush period 825 and second idle periods 830, takes place with event chain like those event class of describing about Fig. 7 therebetween.Yet because the mineralogical composition in the water is different, level of conductivity possibly be different during circulation 810-825.For instance, as shown in Figure 8, flush period 810 appears than those slightly high conductibility shown in Figure 7 with post-flush period 825 in advance.
Fig. 9 illustrates and curve 900 exemplary like that class of a curve shown in Figure 7, and this curve is represented container conductibility desirable during material delivery cycle.Yet in the embodiment depicted in fig. 9, the dosing of material is interrupted between delivery period or suspends.For instance, conductibility is from beginning with consistent level of dosing phases 905, drops into the level consistent with post-flush period 910 and idle periods 915 then.Then, conductibility rises to the level consistent with preparatory flush period 920 and another 925 dosing phase.In some embodiments, such time-out and restart and during system calibration, to realize.For instance, in some embodiments, dissemination system 100 comprises calibration mode, and this pattern considers that at least a part of water and/or water/material solution will use sensor 525 (or another sensor) to test before discharging from dissemination system 100.During calibration mode, calibration chamber possibly be used for collecting water and/or water/material solution.In order to guarantee that calibration chamber do not overflow, the dosing of material can suspend, thereby allows calibration chamber is turned.In case calibration system has reached balance, dosing just can restart.
In some embodiments, pause function is with to restart function maybe usage different.For instance, in some embodiments, solution concentration (that is, be distributed in the per unit water material quantity) is that the downstream (in the rinsing maching that for example, is being associated) at dissemination system 100 are measured.If solution concentration is approaching or reach material concentration set point (for example, being stored in the concentration set point in the controller 505), dissemination system 100 can suspend, simultaneously the agent number of the actual material of being sent of verification.Then, can suitably calibrate this dissemination system 100 once more.For instance, system 100 can recomputate the agent number of material requested for the conductibility that increases the rinsing maching storage tank by predetermined quantity gradually.Other calibration program once more also is possible.
In another embodiment, suspending and restart function possibly be the (see figure 3) of when giving container 110 two kinds of material delivery, using.For instance, in some embodiments, 0-240 agent first material is that the another kind of material of every separated potion is presented.Because the restriction of power and/or driver part can only be presented a kind of material at every turn.Therefore, sending of a kind of material possibly suspended, and meanwhile accomplishes sending of another kind of material.
In the another one embodiment, suspend and restart the dissemination system (or conductivity sensor be switched off time) that function possibly be used to not comprise conductivity sensor.In such embodiment, the downstream rinsing maching that is associated possibly send to dissemination system to triggering signal in the request delivery materials.If triggering signal is lost between delivery period or interrupted, the dosing of material possibly suspended before triggering signal is recovered.
Figure 10 illustrates curve 1000 exemplary, and this curve is represented container conductibility desirable when during material delivery cycle, using various conductivity threshold.Similar with curve 700 shown in Figure 7, curve 1000 comprises idle periods 1005, preparatory flush period 1010, dosing phase 1015, post-flush period 1020 and second idle periods 1025.Yet; Curve 1000 (for example also comprises water conductivity threshold 1030; With respect to doing the conductibility of conductibility with side-play amount sum water), dried conductivity limit 1035, chemical conductivity threshold 1040 conductibility of water conductibility and side-play amount sum chemicals (for example, with respect to) and water conductivity limit 1045.
Doing conductivity limit 1035 is effectively to set with the dried conductibility of sensor 525 monitorings in order to guarantee.For instance, the dried conductibility of container 110 should confirm to do the effectively dried conductivity limit of conductivity values below 1035 at controller 505.Usually, doing conductivity limit 1035 is the boundaries of fixing.
In other embodiment, possibly set more or less conductivity threshold.For instance, in one embodiment, do not use absolute conductivity thresholds, only stay water conductivity threshold 1030 and chemical conductivity threshold 1040.Alternatively, more conductivity threshold possibly be implemented, for instance, and maximum chemical conductivity threshold.
Figure 11 illustrates curve 1100 exemplary, and this curve is represented certain material delivery cycle, and the material residue has been attached on the sensor 525 and has been become dry in this circulation.For instance, shown in figure 11, conductibility is slightly higher than desirable conductivity trace 1110 during first idle periods 1105.Yet, because this conductibility is not still dried conductivity limit (for example, the conductibility of residue is even as big as breaking through the degree of doing conductivity limit 1115) below 1115, so the operation of dissemination system is not changed.Therefore, conductibility through preparatory flush period 1120, dosing phase 1125, post-flush period 1135 and second idle periods 1140 all with similar in ideal conductivity shown in Figure 7.Therefore, the distribution erroneous condition is unrecognized, because conductibility remains in the threshold range in whole material distribution circulation at any time.In some embodiments, water is being enough to remove the residue on the sensor 525 during the post-flush period 1135.Thereby the conductibility during second idle periods 1140 possibly be lower than the conductibility during first idle periods 1105.
Figure 12 illustrates curve 1200 exemplary, and this curve is represented certain material delivery cycle, and the material residue has been attached on the sensor 525 and has been remained wet in this circulation.For instance, shown in figure 12, conductibility is surpassing absolute or maximum water conductibility limit 1210 (except doing conductivity limit 1215 and chemical conductivity threshold 1220) during the idle periods 1205.During preparatory flush period 1225, the water cleaning has the sensor 525 of material residue, so conductibility begins to descend.To after the water conductivity limit is 1210 below, dosing phases 1230 begin, so material is sent in conductivity falls.If conductibility does not drop into the water conductivity limit below 1210, as about Figure 16 in more detail as described in, material possibly not sent during the dosing phase 1230.After the dosing phase 1230, water begins to remove the material residue from sensor 525 from post-flush period 1235, allows conductibility to descend whereby.In some embodiments, the distribution erroneous condition possibly be to discern owing to conductibility during idle periods 1205 raises at first.This distribution erroneous condition can use one or more visions and/or audible signal (for example, the light with the different colours classification of status indicator 520) to point out.Yet as stated, material delivery is owing to conductive change during preparatory flush period 1225 still is allowed to take place.In some embodiments, every kind of erroneous condition of distributing cycle period identification at material is also write down or is stored in the controller 505 (or another accessible memory location), so that the erroneous condition of user's ability access stored.Like this, the user possibly be able to discern mistake in the past with comparalive ease and use that knowledge to repair or overhaul this dissemination system.
Figure 13 illustrates curve 1300 exemplary, and this curve is represented certain material delivery cycle, and sensor 525 has been disconnected in this circulation, or container 110 gets clogged at the upper reaches of sensor 525.For instance, shown in figure 13, conductivity trace 1305 be relatively flat and also be lower than conductivity threshold 1310.As a result, the distribution erroneous condition is identified and can use one or more visions and/or audible signal to point out.In some embodiments, as as described in Figure 20, the distribution erroneous condition that each identifies is to use distinct vision and/or audible signal to point out, this allows the difference between the distinguish erroneous condition.For instance, in the embodiment depicted in fig. 13, distribution erroneous condition " anhydrous " is (for example, being lighted with the corresponding color lamp of erroneous condition " anhydrous ") with status indicator 520 identifications and demonstration.Therefore therefore, actually or the user can discern sensor 525 soon and is disconnected and can sense conductivity supplies water.As stated, error condition flag also possibly set in controller 505.In other embodiment, in case the distribution erroneous condition is identified, controller 505 just can be launched the signal (for example, make the parts of dissemination system ineffective) of correction operations.
Figure 14 illustrates curve 1400 exemplary, and this curve is represented certain material delivery cycle, and water system breaks down during material delivery in this circulation.For instance, conductibility is followed the vestige 1415 of ideal conductivity approx during idle periods 1405 and preparatory flush period 1410.Yet after the dosing phase 1420, conductibility is disobeyed and is thought that according to reason conductivity trace 1415 descends.This is because water system is removed, thereby the material that allows during the dosing phase 1420, to send is stayed in the container 110 and with sensor 525 and contacted.In the embodiment depicted in fig. 14, distribution erroneous condition " blocked flow path " or " dispensing device obstruction " are with status indicator 520 identifications and show.In some embodiments, after this erroneous condition is identified, additional dosing will not be done.For instance, the user possibly have to block and/or admit one's mistake (for example, through removing the error flag in the controller) artificial before removing of dissemination system resume operations.
Figure 15 illustrates curve 1500 exemplary, and this curve is represented certain material delivery cycle, and the slurry that in this circulation, comprises work sheet and water has been attached on the probe of sensor 525 and has been become dry.For instance, during idle periods 1505, conductibility is to be usually less than to do conductivity limit 1510, thereby shows that container 110 does not have water and material usually.Yet during preparatory flush period 1515, because dry substance is moistening once more on sensor 525, conductibility rises to absolute or maximum water conductibility limit more than 1520.In addition, in the embodiment depicted in fig. 15, conductibility did not drop into the water conductivity limit below 1520 before dosing phases 1525 beginning.Thereby distribution erroneous condition " dispensing device obstruction " is discerned with status indicator 520 and is pointed out.In some embodiments, when identification error situation " dispensing device obstruction ", controller 505 stops material delivery.Thereby conductibility continues to descend relatively lentamente.In some embodiments, even delivery materials not, water also continues to flow.These current can be made contributions for conductibility descends, because some slurries will be removed near the zone the sensor 525.As as described in Figure 14, the user possibly have at the artificial before removing slurry of dissemination system resume operations and/or admit one's mistake.
Figure 16 illustrates curve 1600 exemplary, and this curve is represented certain material delivery cycle, and water system is disabled and slurry has been attached to the probe of sensor 525 in this circulation.For instance, during idle periods 1605, owing on the sensor 525 slurry is arranged, conductibility is greater than absolute or maximum water conductibility limit 1610.Therefore, can discern certain erroneous condition.Yet as as described in Figure 12, controller 505 is attempted through release water cleaning sensor 525 during preparatory flush period, rather than shut-down operation.In embodiment shown in Figure 16, water system be disabled (for example, water is not supplied to inlet channel 140, and magnetic valve 145 has broken down, or the like.), and therefore, level of conductivity remains on the water conductivity limit more than 1610.Therefore, erroneous condition " dispensing device obstruction " is discerned by situation indicator 520 and is pointed out.In addition, controller 505 stops material delivery or dosing to take place.Moreover, continuing before operation can take place user possibly have to artificial removing slurry and/or solution water system problem.Alternatively, if use numerous sensors (for example, shown in Fig. 4 B), sensor can be used for current and the help of perception inlet makes that problem is isolated to be " anhydrous " situation or " dispensing device/blocked flow path " situation.
Figure 17 illustrates curve 1700 exemplary, and this curve is represented certain material delivery cycle, and material to be distributed is unavailable (for example, the supply of material is used up) in this circulation.For instance, shown in figure 17, during idle periods 1705, conductibility is lower than water conductivity threshold 1710.During preparatory flush period 1715, conductibility rises to the consistent level of conductibility with the make-up water water of inlet channel 140 (for example, from).Yet during the dosing phase 1720, conductive increase is not similar with ideal conductivity trace 1725, but conductibility remains on the level (conductibility does not rise to and is higher than chemical conductivity threshold 1730) of preparatory flush period 1715 approx.Therefore, distribution erroneous condition " shortage product " is discerned by situation indicator 520 and is pointed out.In some embodiments, controller 505 possibly attempt continuing to do material delivery (for example, through rotation end socket 115 another doses of distribution) in order automatically to make dissemination system 100 be ready to ensuing material delivery.Yet if distribution erroneous condition " shortage product " is during material delivery cycle afterwards, to discern, controller 505 possibly make operation stop and requiring user's manual work that container 105 is filled up or change container 105 once more with material.
Figure 18 illustrates curve 1800 exemplary, and this curve is represented certain material delivery cycle, and the material supply is used up in the middle of powder is sent in this circulation.Shown in figure 18, conductibility is followed ideal conductivity trace 1805 from start to finish in half material delivery cycle, but during the dosing phase 1810, descends apace along with material runs out.Thereby conductibility drops to during the dosing phase 1810 and is lower than chemical conductivity threshold 1815, so distribution situation mistake " shortage product " is discerned by situation indicator 520 and pointed out.Be similar to embodiment shown in Figure 17, controller 505 possibly attempt continuing to do material delivery (for example, through rotation end socket 115 another doses of distribution) in order automatically to make delivery system 100 be ready to ensuing material delivery.Yet if distribution erroneous condition " shortage product " is during material delivery cycle afterwards, to discern, controller 505 possibly make operation stop and requiring user's manual work that container 105 usefulness materials are filled up once more.
Figure 19 illustrates curve 1900 exemplary, and this curve is represented certain material delivery cycle, and the part that container 110 leads to outlet conduit 150 in this circulation is by the material obstruction, but water still can ooze out through this obturator.For instance, during idle periods 1905, conductibility is lower than water conductivity threshold 1910.Yet during preparatory flush period, conductibility rises to the point that is higher than water conductivity limit 1915.Therefore, distribution erroneous condition " dispensing device obstruction " is discerned by situation indicator 520 and is pointed out.Because the distribution erroneous condition of " dispensing device obstruction " appears, thus do not attempt material delivery, but water continues supply.Therefore, conductibility remains almost constant during dosing phase 1920 and post-flush period 1925.After water supply is interrupted, conductivity falls, but be kept above water conductivity limit 1915.The user possibly have at the artificial before removing obturator of dissemination system resume operations and/or admit one's mistake.Yet in some embodiments, this material delivery cycle will be repeated when attempting to remove obturator.In such embodiment, possibly during preparatory flush period, press material delivery cycle (for example, three delivery cycle) the supply water of given number.Yet, in some embodiments,, after the material delivery cycle of three failures, will no longer supply water during the flush period in advance for fear of overflow situation.Thereby the user possibly have to before the dissemination system resume operations, manual work to remove obturator and/or to admit one's mistake.
Figure 20 illustrates the imitated embodiment of the status indicator 2000 that is used for dissemination system (for example, dissemination system 100), comprising three kinds of materials (for example, detergent material, disinfection agent material and rinse aid material).In other embodiment, status indicator 2000 possibly be applicable to and comprise than shown in Figure 20 those and Duoing or the system of few material.Status indicator 2000 generally includes and the three kinds of corresponding detergent material indicator lamp of material elements 2005, disinfection agent material indicator lamp element 2010 and rinse aid indicator lamp element 2015.In addition, in some embodiments, status indicator 2000 comprises information display (for example, the display of LCD or similar type).In other embodiment, status indicator 2000 possibly comprise than shown in Figure 20 those Duos or few lamp (or other indication components and parts).For instance, in some embodiments, status indicator possibly comprise other optical element (for example, the majority of the light element of different colours).Alternatively, status indicator possibly comprise less optical element (for example, a kind of independent light element that changes color).
Usually, modulation element 2005-2015 can be used for pointing out the situation of dissemination system and/or the situation of every kind of material.For instance, in one embodiment, as that kind that is described in more detail below, modulation element 2005-2015 changes color according to the situation of dissemination system.For instance, green light can be pointed out the suitably operation of this dissemination system.Yet if certain erroneous condition is identified, light possibly change color, so that point out to exist certain erroneous condition to the user.
For instance, in one embodiment, identifying certain erroneous condition (for example, " container obstruction " situation) afterwards, yellow flash is used for pointing out this material dissemination system lost efficacy (that is, during the dosing phase will not work sheet).In order to remove erroneous condition and to proceed dissemination system operation, give the power supply of the dissemination system 100 first interruption of possibly having to, and then restore electricity.In other embodiment, erroneous condition possibly be to use another kind of method to remove, for instance, and through being positioned at the input unit (for example, " removing fault " button) on the status indicator panel.
In some embodiments, this dissemination system passes before not incapacitation before mistake that identifies given number or fault or in the preset time circulation.For instance, the erroneous condition of confirming can registered and/or store to controller in the identification error situation, and after three continuous erroneous condition, make this dissemination system incapacitation.Such embodiment can minimize because of the dissemination system incapacitation that the erroneous judgement erroneous condition causes.
